Optimized (defragmented) data
Unoptimized data that:
	Belongs at beginning of drive
	Belongs in middle of drive
	Belongs at end of drive
	Free space
	Data that will not be moved
	Bad (damaged) area of the disk
	Data that's currently being read
	Data that's currently being written
Game-only:
	You (the read head)
	Goal cluster — touch to clear the level
	Checkpoint — saves your respawn spot
	Fragile — cracks after one step
	Coin — collect for points and protection

Each box represents one disk cluster.

Objective

Reach the magenta goal stripe at the right edge of each level. Five levels in total. Coins give you points and some protection.

Controls

• Move / Jump: Arrow keys or WSAD. Space also jumps. Double-jump allowed.
• Pause: P, or click the Pause button

• Move: drag your left thumb on the D-pad
• Jump: tap your right thumb anywhere outside the D-pad
• Pause: tap the Pause button
• Played in landscape orientation.

Watch for

• Green flash: a cell is being read — about to disappear
• Red flash: a free cell is being written — about to become solid (standing in it = crushed)
• Over time, the back of the disk fills in. Don't dawdle and don't backtrack too far.
